This recipe is from the Reader's Digest, Magic foods for better blood sugar book. I don't eat a lot of pasta because let's face it, it's just not that healthy, or low fat. But there are times where I crave pasta and am always looking for a healthy, fast and tasty version to have on hand. This serves nice with a side salad and a piece of low glycemic bread such as pumpernickel or sourdough. Instead of butter, a low fat ricotta mixed with a tsp of olive oil and some chili flakes is a nice low glycemic spread.
There is also a variation here for Penne with Spinach, Ricotta and Lemon, however I have not tried this variation.
